Portable Foundation Cream Container with Elastic Air Inflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable foundation cream containers suffer from issues such as powder being blown during application, leading to a messy environment, and incomplete cosmetic discharge due to repeated sponge contact, which can result in contamination.
Innovation Solution
A portable foundation cream container design featuring a container main body with a lid, an inner container with discharge ports, a push plate, and a one-way check valve, along with an air inflow passage and shape resilient body, allowing controlled and complete discharge of cosmetic liquid through the ports, preventing contamination and ensuring efficient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If powder foundation is rubbed with a puff in a portable container, then the foundation can be applied to the skin, but powder is blown during the process making the container and surroundings messy
Solution Approach 1:
The patent introduces a flexible membrane that separates the powder container from the puff. This membrane allows the puff to press against the powder without direct contact, preventing powder blowout while maintaining the application function. The membrane acts as a barrier that controls the interaction between the puff and powder, solving the messiness problem.
Solution Approach 2:
The flexible membrane serves as an intermediary element between the puff and the powder foundation. Instead of direct contact, the membrane mediates the interaction, allowing force transmission from the puff to the powder while preventing powder particles from being blown outward. This intermediary structure resolves the contradiction between application ease and powder control.
2Quantity of substance
If the sponge is pressed strongly to discharge cosmetics, then more cosmetics can be put on the puff, but cosmetics cannot be exhausted completely and contamination occurs
Solution Approach 1:
The patent divides the cosmetic container into separate compartments: a powder storage chamber and a puff chamber separated by a flexible membrane. This segmentation allows independent control of each compartment, enabling complete discharge of cosmetics from the powder side while preventing contamination of the puff side. The segmented structure ensures cosmetics are fully utilized without cross-contamination.
Solution Approach 2:
The flexible membrane is designed as a disposable or replaceable component that can be easily replaced when contaminated. This approach allows the system to maintain hygiene by replacing the membrane rather than cleaning the entire assembly, ensuring complete cosmetic discharge while preventing contamination through regular replacement of the separating element.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents powder blowouts, ensures complete cosmetic discharge, and reduces contamination risks, providing a cleaner and more efficient application process.
Implementation Method 1
a shape resilient body formed outside the container main body in which the air inflow passage is formed, wherein the shape resilient body has a vent hole at the center of the shape resilient body and is formed to be compressible and recoverable
Implementation Method 2
a one-way check valve provided at one side of the air inflow passage to allow air introduced from the outside of the container main body through the air inflow passage to flow into the inner container and to prevent air movement in the opposite direction
Implementation Method 3
a push plate for supporting the cosmetic liquid and pushing up the cosmetic liquid and discharging the cosmetic liquid through the discharge ports
